초록

지구물리학적 현상을 이해하고 지반공학 관련 문제를 해결하기 위한 주요 요소로서 전단파속도가 강조되어 왔다. 특히, 내진설계와 내진성능평가를 위한 지반지진공학 분야에서 전단파속도의 중요성이 보편적으로 인지되고 있다. 국내 183개소 부지들에서의 다양한 현장 탄성파시험 수행을 통해 대상 조사 부지들에서의 대표적 지반 동적물성으로서의 깊이별 전단파속도 분포들을 결정하였다. 대상 부지들의 지하 토사와 암반 지층을 지반지진공학적 간편 활용을 위한 매립토, 퇴적토, 풍화토, 풍화암 및 기반암의 5 종류 지반지층으로 재분류하였다. 현장 탄성파시험의 전단파속도 분포들을 종합하여 5 종류 지반지층들의 평균적인 전단파속도 주상들을 도출하였으며, 이를 토대로 지진학 및 지반지진공학에서의 유용을 위한 각 지층별 대표 전단파속도 값을 도출하였다.

Shear wave velocity is commonly invoked in explaining geophysical phenomena and in solving geotechnical engineering problems. In particular, the importance of shear wave velocity in geotechnical earthquake engineering has been widely recognized for seismic design and seismic performance evaluation. In the present study, various insitu seismic tests were performed to evaluate geotechnical dynamic characteristics at 183 sites in Korea, and shear wave velocity profiles with depth were determined to be representative of the dynamic properties at the investigated sites. Subsurface soil and rock layers at the target sites were reclassified into five geotechnical layers: fill, alluvial soil, weathered soil, weathered rock, and bedrock, taking into account their general uses in geotechnical earthquake engineering practice. Average shear wave velocity profiles for the five geotechnical layers were obtained by synthesizing the shear wave velocity profiles from seismic tests in the field. Based on the profiles, a representative shear wave velocity value was determined for each layer, for use in engineering seismology and geotechnical earthquake engineering.
